  • Method and apparatus for measuring the moisture content of a substance
    Patent number: 4845421
    Abstract: The moisture content of a substance (1) on a moving belt (2) is measured as a function of dielectric constant. Two pairs of electrodes (4), (5) are positioned adjacent the belt, an inner pair of electrodes (4) and an outer pair (5), an A.C. potential is applied to the electrodes, the flux from the outer pair (5) passing through the substance (1) at a greater distance than the flux from the inner pair (4).
